Enables transcription corepressor activity. Predicted to be involved in several processes, including negative regulation of hippo signaling; regulation of gene expression; and response to hypoxia. Predicted to act upstream of or within gene silencing by miRNA. Predicted to be located in cell junction; cytoplasm; and plasma membrane. Predicted to be part of transcription regulator complex. Predicted to be active in P-body; adherens junction; and nucleus. Is expressed in several structures, including adipose tissue; alimentary system; genitourinary system; nervous system; and sensory organ. Orthologous to human WTIP (WT1 interacting protein).
